I do not know the name of this block, but I just love it. I think someone on the Board posted it, but not sure where I picked the pattern up. Here are the directions to making it though. It sounds complicated, but ISN'T it really goes together fast I think. I started with a 4" square - whatever you want for the center of the block. Then cut another 4" square and place these 2 squares right sides together and sew all around the edges using l/4" seam allowance (throughout) then being careful pick up the center of the 2nd square and snip it, then cut to each corner (diagonally) being careful not to cut through the corners where the stitching is. fold out and press with a dry iron-( it will be on the bias and a steam iron will probably stretch it) now you have a 5 1/2" block, cut another 51/2" square and lay right sides together again and sew around all the edges, repeat the snipping and cutting at the diagonal press, now you have a 7" square or block, next cut a 7" square and place right sides together again and sew around all 4 sides, snip and cut diagonally, press - Walla a perfect 9" block. NOTE Do not snip the little dog ears after adding each new square, as they help with putting the next square on, don't know just why, but they do. I tried using a 6 1/2" center block and ended up with a 14 1/4" block. Unless you want an extra large block, I suggest starting with the 4". I have just finished making these blocks and am in the process of putting the blocks together - no sashing between blocks, as when they are sewn tegether they make another pattern and these blocks go together great. I love this block. Will post pic. when I get the quilt top completed and get a pic of it. Whoever came up with this method Hooray for them. I love it. This is also an easy way of using some scrap fabrics. Have fun on your retreat!!
